I have been using "preview pane" in file explorer forever. However, for some unknown reason, the preview pane for pdf files have become very small, to the point where the pdf file preview pane is too small and unreadable. preview pane for all other files appears to be ok (large enough as before). this is only affecting pdf files.
I have uninstalled and reinstalled Adobe reader.
I am looking for suggestions to get back to where the preview pane of pdf files is as large as before
